i had this issue recently, i believe it begun from 15 April 2022. Since then the automatic deployement is broken for a project that i deployed from GitHub. You can find below the Error that shows up after trying to connect to github (on new app) , or manual deploy (on old app)
And here you can find some old notifications about automatic deployment that i'm still having it at the moment

And here the app logs :
